Original abstract
Formation of oxide layers on the surface is inherent part of steel production. The presence of the oxide layer primarily influences the surface quality and material losses during steel processing. The influence of the oxide layer on the cooling intensity and homogeneity is not frequently reported but even thin layers of oxides can significantly modify the cooling intensity. Although the cooling intensity is primarily affected by spray parameters as pressure and coolant impingement density, the influence of the oxide layer should be also considered for optimal setting and regulation of the secondary cooling zone. The influence of the oxide layer on the heat transfer coefficient and Leidenfrost temperature is investigated in this paper. Laboratory measurement compares the spray cooling of oxide-free steel surface and oxidized steel surface. Results of measurement also show the impact on the spray cooling homogeneity due to local breaking up of the oxide layer.
